Notes: w/ 2-Pin Connector - There is 2-different versions of this fan motor, both have the mounting flange adaptor that allows this fan motor to be used on the earlier models that originally came with fan motor #3506325, while both will work, it may take some wiring mods to be made.The OEA version only has the 2-pin pigtail ,the AIR/ VIS version also contains the wiring adaptor to convert the 1-pin ( old style ) to the newer 2-pin style. The OEA version should be a direct replacement for 1989.5 + 740/940 Models.
